Our objective was to assess the link between season of birth, neonatal 25-hydroxyvitamin D3, and adult cardiovascular disease; we report higher neonatal 25(OH)D3 associated with higher levels of cholesterol (in women), fasting insulin, and triglyceride, and with a higher risk of overweight at 35 years of age, but not with other adult cardiovascular disease risk factors.

Blood lead level may be related with cardiovascular disease in healthy older men through its association with tumor necrosis factor receptor-2 (TNFRSF1B); in addition, the magnitude of the association of blood lead level with TNFRSF1B level increased with age in the study population.

Both low and high concentrations of neonatal vitamin D are associated with increased risk of schizophrenia, and it is feasible that this exposure could contribute to a sizeable proportion of cases in Denmark.

We describe associations among basic characteristics, seasons, and diseases with serum levels of 25-hydroxyvitamin D in patients and note that 25(OH)D3 levels are low while 25(OH)D2 levels are high among patients with lung diseases, dyskinesias, and coronary heart disease, and participants with diabetes and cerebral infarction have higher 25(OH)D3 serum concentrations compared with lung disease patients.
